The Dockerfile shouldn't run any processes that need to persist between 2 stages as each stage will be created in a new instance. You can either do fancy one-liner bash scripts (my favorite) to configure simple service / app startup scripts, or include a configuration file from elsewhere using the `ADD` directive. The only non ephemeral command should be the final `CMD` or `ENTRYPOINT` as far as I can work out. I too am just learning this stuff, but that should hopefully help you out!
